vAni object of the invention-is to .provide in-a valve of the character described and 'v'rherein the-motor is contained in a chambersep'arated from :the' valve'casing by a common wa1l,"means sotinter'connecting the valve closuremeans and the motor that, while the desired equalization of :pressure between the motor-chamber and the interior of the casing 518 permitted, the motor is protected from such flow-velocity of the fluid as-might affect the motor to-reduce the flowcapacity and pressure-ratings .of the valve; the motor .iurther being protected from the harmful effectof foreign matter carried by thev fluid. Other objects and advantages fthe invention will be found in the description, the drawing, and the claims; and, foriullundersta-ndingof theinvention, reference is to be had to the following detailed -;description :and accompanying drawing, wherein:

When the solenoid 41 is energized, its plunger is attracted (to an internally-stopped position) so that the lever is rocked against the force of spring 50 to depress closure-stem 24 and release the other stem 33; communication thus being established between the common connection l2 and the other connection l3 by way of passages l5-l6, distribution chamber I1, port-member openings 21 and recess 26, bore l9, and passage I8.

The embodiment of my invention herein shown and described is obviously susceptible of modification without departing from the spirit of the invention, and I intend therefore to be limited only by the scope of the appended claims.

I claim as my invention:

1. In a fluid control valve: a casing having a plurality of individual passages and a common passage, all for conducting fluid with respect to the valve; means in said casing forming a distribution chamber in communication with said common passage; individual closure means for controlling communication between said distribution chamber and said individual passages;

means forming another chamber at the exterior of the casing separated from said distribution chamber by a common wall; and means in said other chamber for operating said closure means and including means extending through openings in said common wall, said openings being such as to permit gradual equalization of pressure between the chambers.

2. In a fluid control valve: a casing having a plurality of individual passages and a common passage, all for conducting fluid with respect to the valve; means in said casing forming a distribution chamber in communication with said common passage; individual closure means for controlling communication between said distribution chamber and said individual passages; means forming another chamber at the exterior of the casing separated from said distribution chamber by a common wall; and means in said other chamber for operating said closure means and including a plurality of rods individually cooperable with the closure means and reciprocable in openings through said common wall; the fit of said rods in said openings being such. as to pretribution chamber in communication with saidv common passage; means forming a partition between said distribution chamber and each of said individual passages and having a plurality of ports communicating with the individual passages; a closure for each of said ports; means forming another chamber at the side of said distribution chamber opposite said partition and separated from the distribution chamber by a common wall; said partition having a plurality of projections, coaxial with the individual ports, fitting in openings through said common wall; and means in said other chamber for operating said closures and including means guided in openings through said projections; the fit of said projections in said wall-openings being such as to permit gradual equalization of pressure between the chambers.

4. In a fluid control valve: a casing having a plurality of individual passage and a common passage, all for conducting fluid with respect to the valve; said casing having a recess in a surface thereof and in communication with said common passage; a plate covering said recess so as to form therewith a distribution chamber; said casing having in the side wall of said recess opposite said plate a plurality of ports communicating with said individual passages; a closure for each of said ports; means forming another chamber at the exterior of the-casing and defined in part by said plate; and means in said other chamber for operating said closures and including means extending through openings in said plate; said openings being such as to permit gradual equalization of pressure between the chambers.

5. In a fluid control valve: a casing having a plurality of individual passages and a common passage, all for conducting fluid with respect to the valve; said casing having a recess in a surface thereof and in communication with said common passage; a plate covering said recess so as to form therewith a distribution chamber; said casing having in the side wall of said recess opposite said plate a plurality of ports communicating with said individual passages; a closure for each of said ports; means forming another chamber at the exterior of the casing and defined in part by said plate; and means in said other chamber for operating said closures and including a plurality of rods individually cooperable with said closures and reciprocable in openings through said plate; the fit of said rods in said openings being such as to prevent surge of fluid between the chambers of a magnitude sufficient to aifect said operating means.

6. In a fluid control valve: a casing having a plurality of individual passages and a common passage, all for conducting fluid with respect to the valve; said casing having a recess in a surface thereof and in communication with said common passage; a plate covering said recess so as to form therewith a distribution chamber; said casing having in the wall of said recess opposite said plate a plurality of openings communicating with said individual passages; a valve port member secured in each of said openings and having a projection fitting in an opening through said plate; a reciprocable closure cooperable with each of said port members and each having a stem guided in an opening through the projection of the port member; means forming another chamber at the exterior of the casing and defined in part by said plate; and means in said other chamber, engageable with said stems, for operating said closures; the fit of said projections in said plate-openings being such as to permit gradual equalization of pressure between the chambers.
